我正在尝试在客户控制器中测试put方法。问题是assigns(:customer)总是返回nil,以便第一次测试失败。然而,第二个测试工作得很好,所以我不明白为什么第一个测试失败,因为从更新方法中的参数中检索了正确的客户。
describe "PUT #update" do
before :each do
@customer = create(:customer, user: @user)
end
context "with valid attributes" do
it "locates the requested customer" do
put :update, id: @customer.id, customer: FactoryGirl.attributes_for(:customer).merge({user_id: @user.id})
assigns(:customer).should eq @customer
end
it "should save customer to the database" do
put :update, id: @customer, customer: {name: 'lorem', mail: 'lorem@gmail.com', address: 'lorem_address', phone:@customer.phone, user_id: @customer.user.id}
@customer.reload
expect(@customer.name).to eq 'lorem'
expect(@customer.mail).to eq 'lorem@gmail.com'
expect(@customer.address).to eq 'lorem_address'
end
end
FactoryGirl.define do
factory :user do
email {Faker::Internet.email}
password {Faker::Internet.password(10)}
end
end
FactoryGirl.define do
factory :customer do
association :user
name Faker::Name.name
sequence(:mail) {|i| "example#{i}@example.com"}
address Faker::Address.street_address
phone Faker::PhoneNumber.phone_number
end
end
def update
debugger
customer = Customer.find(params[:id])
if customer.update_attributes(customers_params)
flash[:success] = 'Customer information updated successfully'
redirect_to customers_path
else
@customer = customer
render :edit
end
end

从此post
assign是一个哈希,可以在Rails测试中访问,包含所有 此时可供视图使用的实例变量......
关键字是instance variables
,即以@
开头的变量。
将update
操作修改为以下内容会使测试通过
def update
debugger
@customer = Customer.find(params[:id])
if @customer.update_attributes(customers_params)
flash[:success] = 'Customer information updated successfully'
redirect_to customers_path
else
render :edit
end
end
